L'écran d'affichage (22) est monté sur un cadre (23) pouvant à son tour être monté de manière facilement démontable sur un support (37) monté pivotant sur le boîtier (21). Le cadre (23) renferme un second circuit électronique apte à maintenir automatiquement l'écran d'affichage (22) à l'état allumé même lorsque le cadre (23) est détaché du boîtier (21). Des connecteurs électriques sont prévus dans la partie inférieure du cadre (23) et à l'intérieur du siège (41) du support (37), et destinés à coopérer lorsque le cadre (23) est mis en place dans le support (37) et que le circuit électronique monté à l'intérieur du cadre (23) est, de ce fait, raccordé au circuit électronique monté à l'intérieur du boîtier (21).
